Abstract

The utility model discloses a radiotherapy particle endoscope implanting device which comprises an implanting needle 1, a catheter 2 and a hard sleeve tube 4, wherein the front end of the catheter 2 forms a tip edge shape and the back end is provided with an implanting needle interface 3. The sleeve tube 4 is sheathed at the outer part of the catheter 2. The implanting device with a structure can carry out interventional therapy for the local tumor of hollow cavity viscera of a stomach, an esophagus, etc.

Description

Radiotherapy particle scope implantation device

Technical field

This utility model relates to a kind of radiotheraphy device, especially is a kind of radiotherapy particle scope implantation device.

Background technology

Radioactive particle is implanted in the tumor body, treatment for local tumor has better action, the particle implantation device of prior art must carry out under the guiding of CT or B ultrasonic when implanting the chemicotherapy particle, complicated operation, equipment and technology requires high, and only can be used for the internal organs that percutaneous puncture arrives, as liver, pancreas etc., hollow organs such as stomach, esophagus are then inapplicable.

Summary of the invention

The purpose of this utility model is to provide a kind of radiotheraphy device that can adapt to the hollow organ interventional therapy, a kind of radiotherapy particle scope implantation device.

This utility model is achieved in that a kind of radiotherapy particle scope implantation device, comprises the hard sleeve of implant needle, conduit and hollow, and catheter proximal end is sharp bladed, and the rear end is the implant needle interface, and sleeve pipe is placed in the outside of conduit.

This utility model and scope are used, biopsy pipe by scope enters focal zone, before the biopsy pipe that inserts scope, earlier implant needle and conduit are retracted in the hard sleeve, prevent that the blade of conduit from stabbing the minute surface or the biopsy pipe of scope, this device can directly inject the radiotherapy particle in the tumor body at direct view under endoscope, can carry out interventional therapy to the local tumor of hollow organs such as stomach, esophagus.

Description of drawings

Accompanying drawing is this utility model cross-sectional schematic.

The specific embodiment

As shown in the figure, conduit 2 front ends are sharp bladed, and the rear end is an implant needle interface 3, and during use, implant needle 1 penetrates conduit 2 by implant needle interface 3, and hard sleeve 4 is placed in the outside of conduit 2.Hard sleeve 4 rear ends are handle 5, are convenient to hold, and conduit 2 length are longer than sleeve pipe 4.Hard sleeve 4 can adopt duroplasts to make.

During use, under the direct-view of scope, operate, earlier implant needle 1 and conduit 2 are retracted in the hard sleeve 4, prevent that the blade of conduit 2 from stabbing the minute surface or the biopsy pipe of scope, after biopsy pipe by scope reaches focal zone, inwardly stretch out conduit 2 and implant needle 1, the radiotherapy particle is directly injected in the tumor body along implant needle 1.

Claims

1, a kind of radiotherapy particle scope implantation device comprises implant needle and conduit, and catheter proximal end is sharp bladed, and the rear end is the implant needle interface, it is characterized in that: also comprise the hard sleeve (4) of hollow, sleeve pipe (4) is placed in the outside of conduit (2).
